Specification of Letters Patent.

Patented July 21, 1914.

Application filed March 14, 1913. Serial No. 754,195.

To all whom it may concern Bc it known that I, KARL Ecolier, a subject of the Emperor of Germany, residing at Arbon, Switzerland, have invented new and useful Improvements in Jacquard-Card- Perforating Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

1n the manufactureof jacquard cards for embroidery machines there are two types of machines commonly employed, viz. punching machines for originalsand copying machines. In both machines a paper strip, the so-called jacquard card, is provided with holes by perforating according to a denite system. rl`he mechanisms of the twotypes ofamachines are similar, but .in the first*mentionedfmachine the originals of the jaCquald cardsare perforated, while in the second mentioned machine such originals are copied.

The ypresent invention relates to improvements in such machines, with a view to rendering the construction as, simple as possible. Simplicity'of structure is of great importance in such machinery, since the want `of precision and other defectsdue to the mass of the oscillatingparts, their wear, friction and connection, can be diminishedby reducing vthe mass. Moreover the work ofthe machine attendant is lrendered easier.

By means .of the present improvements exceedingly smooth workingv of the perforating machin-e is attained, and as a consequence an extremely beautiful embroidery can be'produced; forthe quality of jacquard embroidery depends upon the absolute correctness 0f the vjacquard Card, and this again upon the simplicity of the machine y,with which it is produced.

A preferred embodiment of my invention is illustrated in the accompanying drawing, the machine shown being a Vpunchingmachine with two pairs of perforated drums, of the character described in a pending United States patent application, Hippolyt Saurer, Serial No. 660,267 filed Nov. 14, 1911. Parts not necessary for a clear underl standing of the present kinvention have been omitted.

lin the drawing Figure 1 is a view'in vertical section through the punching` mechanism, and Fig. 2 is a plan view of the parts shown in Fig. l, partly in section; while Figs. 3-6 are vertical sectional views showing the sliding needle frame in vario-us positions.

T, T1, T2, T3 are the four drums of the punching apparatus, `operating in two cycles. T, T1 are the drums for selecting or setting the needles e for the production of those .hcl-es inthe card which are to cause vertical motion of the embroidering` frame of the jacquard embroidery machine, while T2, TB are the drums for selecting or setting the needles c1 for the production of those holes in the card which are to cause horizontal rmotion of the frame. The coperation of the drums T, T1 with the needles e, is substantially the same as that of the drums T2 T3 with the needles el. W', Vl are feed rollers for advancing the card strip K. The roller N1 is driven with intermittent positive motion in any suitable manner.

M is the stationary bottom or bed die over which the card strip K travels.

a is a punch supporter carrier, which is vertically reciprocable in guides l, 2 by means of levers 8, et, actuated by a shaft 5 which is rocked by any suitable well known means. The punches Z; are loosely suspended` a ypunch 5 provided below each needle e, and each needlefel. In the support a there is mounted the frame CZ, in which are loosely slidable the needles e, el, `the underside of each of vwhich is recessed at a1, a, so as to leave an intermediate:tongue y. The frame (Z iis slidable horizontally to and fro by levers 6, 7, actuated by the shaft 8, which like th-e shaft 5 is oscillatedat intervals by any appropriate means.

The `operation of the ymachine is as follows: The two drums T, T2 are first set, according to the desired length of the stitch, in the manner disclosed in the United States patent application Ser. NONGGOQGT, already referred to. Hereupon the frame d is ymoved toward the left by the levers 6, 7, whereby the needles e, el are set, according to the position of the drums T, T2. If the needles c, el are in alinement with holes in the drums .by-.their headsin the support a there being n T, T2, they will enter the latter and thus will not Vbe shifted in the-'frame d. Should the needles e, c1, however, lie opposite unperforated parts of the drums, T, T2, they will contact with the drum surface and thus will be pushed toward the right in the frame CZ. Thus through the motion of the frame d toward the left, the needles c, el are set, corresponding to the ositions of the drums T,

T2. By rocking te shaft 8 the frame (Z is next drawn back into its central position, the needles c, el maintaining their assumed position relatively lto the frame. Fig.v 4 Shows in the central position of the. frame CZ a needle c which has not been shifted by the drum T, while Fig. 5 is a like view showing a needle c which has been moved by contact with an unperforated part of the drum surface. In the case rof those needles e, el which have not been shifted, the tongues are located vabove the punches as shown 1n Fig. 4; while in the case of those needles c, el which have been moved by contact with the drum surface, the recesses are located above the punches 5, as Fig. 5 shows. Tf then, by rocking the shaft 5 the support a is moved downward, those punches above which tongues g/ are located will perfor-ate holes in the card K, while thosek punches above which recesses a' are located only rest lightly upon the card, receding upward into the recesses @a as the support descends, so that no holes are pierced. Hereupon the support a rises into its normal. position again, and the frame d will, through the short oscillation of the shaft 8 be drawntoward the drums T1, T3, (see Fig. 6), whereupon the procedure is repeated. The needles e, el may also be so formed that it is the pushed needles which bring their punches into operation, while the unpushed ones allow their punches to recede in upward direction. The machine might likewise be constructed to operate in a single cycle, only two drums (e. g., T, T2) being employed. ln such construction the needles are naturally only set at one side, and a device is provided to return all the needles to their normal position again. The needle frame is, in such a machine, pushed out of its normal position in one direction, and the needles are therefore only furnished with a single recess ac or a.

lVhat T claim as new is:

l. In a jacquard cardy perforating 'machine, selecting means, a support or carrier,

means to move the same toward and from the card to be perforated, a frame movable ysupport in which the frame is slidably mounted, punches slidable in the frame, and

means for moving the support to and from the work.

3. Tn a jacquard card perforating machine, a frame, needles shdable therein, aY

Tn a jacquard card perforating machine, a rotatable drum, a frame, horizontal needles slidable in axial direction therein, a support in which the frame is mounted with capability of sliding in horizontal direction, vertical punches axially slidable in the frame below the needles, means for moving the frame to and from the drum, and means for moving the support to and from the work.

5. Tn a jacquard card perforating machine, a rotatable drum, a frame, horizontal, recessed needles slidable in axial direction therein, a support in which the frame is mounted with capability of sliding in horizontal direction, a vertical punch, axially slidable in the frame, located below each needle and adapted to enter the recessed part of the latter, means for moving thel frame to and from the drum, and means for moving the support to and from the work.

6. Tn a jacquard card perforating machine, two parallel shafts, a drum loosely mounted on each shaft, a frame located between the two drums, horizontal Aneedles slidable in axial'direct-ion therein and pre` senting two recesses in their lower edge, a support in which the frame ismounted with capability of sliding in horizontal direction, a vertical punch axially slidable in the frame, located below each needle and 'adapt` ed to enter the recesses in the latter, means for moving the needle frame to and Lfro betweenthe drums, andmeans for movingthe support to and from the work. n

In testimony that I claim the foregoing as my invention, lt have signed my name in presence of two subscribing witnesses.
